[asterisk-users] bug? 'dahdi show channel x' HWEC echo cancellation display is incorrect while not on a call
When doing a 'dahdi show channel X' from the asterisk console, when the line is not part of a call the echo cancellation line ALWAYS says 'currently OFF'. Once a call is in progress, it will change to 'ON'. Is this a bug, or is the behavior by design? My setup: Asterisk 10.10.0 Dahdi 2.6.1 TE820 T1 card In chan_dahdi.cfg: ... echocancel=yes echocancelwhenbridged=yes echotraining=800 ... And in #included chan_dahdi_additional.conf (this is a freepbx install): ... ;;;;;;[3884] signalling=fxo_ks pickupgroupmailbox=3884 at default immediate=no echotraining=800 echocancelwhenbridged=yes echocancel=yes context=from-internal callprogress=no callgroupcallerid=John Doe <3884> busydetect=no busycount=7 accountcodechannel=>73 ... -Justin Killen -------------- next part -------------- An HTML attachment was scrubbed...

From a DAHDI perspective: The echocan chip's channels are allocated on demand during channel setup and de-allocated on channel teardown. -- Russ Meyerriecks Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA direct: +1 256-428-6025 Check us out at: www.digium.com & www.asterisk.org
